TELEGRAPH-lNSULATOR.

SPECIFICATION forming part of Letters Patent No. 332,061, dated December 8, 1885.

Application filed September 17, 1885.

To aZZ whom it nwoy concern:

Be it known that I, BENJAMIN N. DEB- LIEUX, of Bay St. Louis, in the county of Hancock and State of Mississippi, have invented a new and useful Improvement in Telegraph- Insulators, of which the following is a descrip tion.

My invention relates to telegraph-insulators; and it has forits object to provide an insulator that can be readily applied to its support and connected with the line-wire, so as to support the same without wrapping or cutting the wire, and obviating a tie-wire altogether.

It consists in an insulator composed of two longitudinal sections placed together to form a joint in the middle and retaining the wire between them,'with devices for holding the sections together and securing them to their support, as will be hereinafter more fully described.

Figure 1 is a vertical transverse section of the insulator and its supporting-bar, and Fig. 2 is a view of the two adjacent faces of the two sections of the insulator arranged side by sists of twopartsthe male part A, which has i a hook or shoulder at a on its inner face to i set upon the Wire, and the female part B, having a shoulder, b, to support the wire. dividing-line is at the middle of the head portion and inclines in the shank portion, so that the end of shank A is larger, and it has a thread. 0, for holding the insulator to the arm. The part B is held to part A by a collar or ring, D, and is put in place with A by a dow nward movement, which inserts the shank into the hole of the cross-arm of the telegraph-pole. The screw 0 extends below the arm. and has a nut, d, by which part A is drawn down on part B to clamp the wire firmly.

The ring or collar D serves the double purpose of holding the rain-shed 6 out of contact with cross-arm or support F, and also holds the two sections A and B together while be ing inserted in the support, and in the event of shrinkage in crossarm hole retains both parts of the insulator closely fitted together.

IVhen the two sectionsAandB are inserted Serial No. 177,397. (No model.)

in the collar D, with the collar resting on the arm F, and the shanks of the two sections protruding below the arm, the nut d is applied to the thread on the end of section A, and as section B has no thread, but is held up by the collar D, it will be seen that when the nut is turned to a bearing against the lower side of arm F it pulls section A down and causes its hook a to press down upon the wire and tightly clamp it against the shoulder 0.

Having thus described my invention, what I claim as new is 1. A telegraph-insulator made in two parts, A and B, in combination with ring or collar D, for binding the faces of the two parts firmly together and holding the water-shed 6 above the support, substantially as shown and described.

2. The male part A, with a screw-thread upon its extremity, in combination with female part B, having no screw-thread, substantially as and for the purpose set forth.

3. The combination, with the two-part insulator and its supporting-arm, of a device for moving one of the insulator parts, and causing them to grasp and firmly hold the wire, substantially as herein shown and described.

at. The combination, with the two-part insulator and the supporting-arm, of a nut arranged to operate upon the thread of the male The part and draw it down upon the female part by pressure of the nut against the under surface of the arm, substantially as described.

5. The male part A, constructed with in clined faces and with a hook to engage the wire, in combination with the female part B, having inclined faces and shoulder I), substantially as described.

6. A telegraplrinsulator consisting of two parts, one of which is provided with inclined faces, a hook to engage the wire, a shank to fit the supportingarm and screw-thread, the other part provided with inclined faces, a shoulder to receive the wire, and shank ring or collar and nut, all substantially as described.
